Benefits of technology
The present invention is a safe and efficient process for dissolving and neutralizing solid nitrocellulose propellants and plasticized military munitions. The process is faster, safer, less expensive, and environmentally friendly compared to current methods. The resulting solution can be safely disposed of as waste water or soil, and the decontaminated equipment attains safe criteria. This process provides a safer and more efficient solution for disposing of solid nitrocellulose propellants and plasticized military munitions.
Problems solved by technology
Currently there are no environmentally sustainable methods of safely disposing of solid nitrocellulose propellants and plasticized military munitions except by blowing them up (detonating) or burning them.
Both of these practices are inherently dangerous, result in toxic byproducts and require the materials to be moved to safe location and stored until they are required to be disposed of.

Nitrocellulose propellants and plasticized military munitions, equipment, or contaminated soil are placed in a suitable container. A first option consists of adding a strong base to plasticized munitions in a container or militarization / demilitarization equipment or soil containing plasticized munitions or nitrocellulose propellant; adding an organic solvent; and then adding water to mixture. Alternatively, a second option consists of adding organic co-solvent to plasticized munitions in a container or soil containing plasticized munitions or solid nitrocellulose propellant. A strong base is added to mixture and allowed to react. When the reaction stops or is completed, a sulfur based bulk reductant is added to degrade all nitro and amino compounds. The organic solvent is evaporated and recovered for reuse and water is added to the container to make up for the evaporated organic solvent. If pH is higher than 8.5, a suitable acid is added to drop the pH to near neutral.
